Weather Forecast Office

Severe Weather of April 10, 2011

Overview

A strong, early spring storm moved across the region on the 9th and 10th of April 2011. On Saturday (April 9th), a warm front was the focus for severe thunderstorm development, and resulted in several tornadoes over northwest Iowa along with large hail and damaging winds.

On Sunday, April 10th, the warm front pushed north across northern Wisconsin. The severe weather focus shifted to a low pressure area and associated cold front that would eventually push through the region. The atmosphere was unstable ahead of the front with favorable winds for storm organization, which included Supercells capable of tornadoes.

Storms started to rapidly develop around 3 p.m. with many producing severe weather within 20 to 30 minutes of initiation. The storm movement was very fast - nearly 70 mph at times.

The severe thunderstorms produced very large hail, damaging winds, and a few tornadoes. Storm surveys confirmed two tornadoes in central Wisconsin (Adams / Waushara Counties) and wind damage in parts of Houston County, MN (near Caledonia) and around Osseo, WI. Hail up to 3 inches in diameter pelted the southern sections of La Crosse as well as neighboring areas in Minnesota. Car, roof, and siding damage was common. Golf ball sized hail fell at the NWS La Crosse office for a brief period.

There were 15 tornadoes in Wisconsin on Sunday, April 10th, which set a new record for the most ever for an April day in Wisconsin. The previous record was set on April 27, 1984, when 10 tornadoes occurred, with 3 fatalities and 42 injuries. That day in 1984 had two F4 intensity tornadoes which have winds of 207-260 mph. On Sunday, the strongest tornado surveyed was EF3 intensity (which has winds around 150 mph). For more information on the Wisconsin tornadoes, see the NWS Milwaukee summary, or the write up from .

Tornado - Necedah, WI
Juneau County

Date	April 10, 2011
Time (Local)	6:14 - 6:21 p.m.
EF Rating	EF1
Est. Peak Winds	95 mph
Path Length	4.5 miles
Max Width	150 yards
Injuries/Deaths	0 / 0
Summary: The tornado first touched down at 614 p.m. at the intersection of Paradise Lane and 25th St W, or about 2.4 miles south-southwest of Necedah, WI. The tornado produced EF0 damage along most of its track east-northeast, but briefly produced EF1 damage /86-95 mph winds/ for about 3/4 of a mile from T Lane through Padre Pio Drive. The tornado rolled over a mobile home and snapped pine trees in this area. The tornado continued east-northeast as an EF0 producing damage to pine trees, crossing County G and ending somewhere in the Wisconsin River around 6:21 p.m. (3.5 miles east-southeast of Necedah). This tornado track was believed to be produced by a second supercell storm that was separate and following just behind the Arkdale-Cottonville storm/tornado. The maximum width of the tornado was 150 yards and the complete track measured 4.5 miles.

Summary: The National Weather Service conducted a tornado survey in Adams County, WI and confirmed a long-lived tornado. The tornado likely occurred between 6:12 p.m. and 6:30 p.m. Sunday, April 10, 2011. The first evidence of a tornado occurred about 3 miles west of Arkdale, WI, just south of Cumberland Ave. It tracked east-northeast increasing in intensity as it hit a farm on 18th Ave. about 1.5 miles west of Arkdale causing extensive damage to barns, trees, and part of the house. A cement silo was knocked over as well. The tornado remained just as intense as it crossed Highway 21 just north of Arkdale hitting nearby homes, irrigation systems, and hundreds of trees. A very distinct convergent pattern was noted in the trees at this location with winds estimated around 125 mph. Several more farms, homes, and areas of trees were hit as the tornado continued toward the south side of Big Roche A Cri Lake near the small community of Cottonville. In some instances cars and mobile homes were flipped or heavily damage. A lake association building on the southwest side of Big Roche A Cri Lake was completely destroyed and numerous center-pivot irrigation systems were twisted or destroyed across the county. EF2 damage was noted as the tornado widened to nearly a half mile wide. It crossed Highway 13 at Cottonville and gradually began to weaken hitting more seasonal homes, trees, and roof tops. By the time the tornado crossed 9th Dr. it had weakened to an EF0 and was 150 yards wide. The weakening trend continued as it moved just south of the Colburn Wildlife area. The total length of the tornado from 3 miles west of Arkdale to 5.5 miles northwest of Coloma: approximately 17 miles. Peak intensity EF2 (125 mph) and maximum width approx. 800 yards.

Summary: A second tornado formed just north of where the Arkdale-Cottonville dissipated, near County Road G and Buttercup Ave in far eastern Adams County, WI. EF1 damage was noted to some homes and areas of trees, especially along Buttercup Ave as the storm tracked into Waushara County. Several center-post irrigation systems were destroyed along with some roof damage to homes and power poles. The tornado weakened to EF0 over most of its path as it continued to areas southeast of Hancock, WI before dissipating.
